Sansevieria hybrid plant named ‘Supsan1402’

ABSTRACT

A new and distinct  Sansevieria  cultivar named ‘Supsan1402’ which is characterized by the combination of pineapple-like foliage with a limited number of arched leaves radiating from a basal rosette, unique coloration and patterning of the foliage, narrow foliage, soft and brittle foliage which will not inflict bodily harm, and the stability of all characteristics from generation to generation. The new variety is a  Sansevieria,  typically produced as an indoor ornamental plant.

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Sansevieria Thunb.

Variety denomination: The inventive variety of Sansevieria disclosed herein has been given the variety denomination ‘Supsan1402’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2014/2946, filed Nov. 14, 2014, which is herein incorporated by reference.

BACKGROUND OF THE INVENTION

Parentage: The Sansevieria variety ‘Supsan1402’ originated as a seedling selection from the controlled pollination of the unpatented, proprietary seed parent, Sansevieria hybrid ‘VH5’, with the unpatented, proprietary pollen parent, Sansevieria ‘MH5’. Both parents were developed by, and are owned by, the inventor and were never commercially released. Said crossing was conducted by the inventor in a small, netted greenhouse in Chonburi, Thailand in December of 2010. Seeds resulting from the cross were harvested and subsequently sown in March of 2011. Resulting progeny were grown to maturity for the evaluation of unique characteristics. Of these progeny, several varieties were selected which exhibited a pineapple-like growth habit with a limited number of arched leaves radiating from a basal rosette, unique coloration and patterning of the foliage, and foliage which was soft and brittle so as not to inflict injury if the plants were to come into contact with a hand or other body part.

After further observation of said candidate varieties, one plant was selected in March of 2012 which exhibited a combination of unique characteristics suitable for commercial release. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and propagation, assessing stability of the unique characteristics of this variety. The new cultivar was given the breeder denomination ‘Supsan1402’.

Asexual Reproduction: Asexual reproduction of ‘Supsan1402’ by way of harvesting vegetative ground shoots was first initiated in April of 2012 at Chonburi, Thailand. Access to all plants was restricted, as plants were kept in a greenhouse not open to the public. Through subsequent propagation of vegetative ground shoots, eight generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Supsan1402’ has not been observed under all possible environmental conditions and the phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Supsan1402’. These characteristics in combination distinguish ‘Supsan1402’ as a new and distinct Sansevieria cultivar:

-   -   1. Sansevieria ‘Supsan1402’ exhibits a limited number of leaves;         and     -   2. Sansevieria ‘Supsan1402’ exhibits a pineapple-like growth         habit with a limited number of arched leaves radiating from a         basal rosette; and     -   3. Sansevieria ‘Supsan1402’ exhibits foliage with a unique color         pattern of dark green and silver; and,     -   4. Sansevieria ‘Supsan1402’ exhibits narrow foliage; and     -   5. Sansevieria ‘Supsan1402’ exhibits soft and brittle foliage         which will not inflict bodily harm if plants come into contact         with a hand or other body part.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical foliage of ‘Supsan1402’.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements describe a twenty week-old ‘Supsan1402’ plant grown in a commercial greenhouse in Chonburi, Thailand. The plants were grown under plastic with a 20% shade cloth, thus controlling the amount of sunlight and sheltering said plants from rain.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘Supsan1402’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climactic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).

COMPARISONS WITH SIMILAR SANSEVIERIA CULTIVARS KNOWN TO THE INVENTOR

‘Supsan1402’ is similar in many horticultural characteristics to the commercial variety Sansevieria ‘Farah’ (unpatented in the United States). However ‘Supsan1402’ differs from ‘Farah’ in the following characteristics:

-   -   1. The primary foliage color of ‘Supsan1402’ is dark green,         whereas the primary foliage color of ‘Farah’ is a lighter green         color.     -   2. The secondary foliage color of ‘Supsan1402’ is silver,         whereas ‘Farah’ almost completely lacks a secondary foliage         color.     -   3. The abaxial foliage color of ‘Supsan1402’ is silver and         green, whereas the abaxial foliage color of ‘Farah’ is green.     -   4. ‘Supsan1402’ exhibits thicker foliage when compared to the         foliage of ‘Farah’.     -   5. ‘Supsan1402’ exhibits wider foliage when compared to the         foliage of ‘Farah’.     -   6. The foliage of ‘Supsan1402’ is more arched when compared to         the upright foliage of ‘Farah’.     -   7. ‘Supsan1402’ produces fewer ground shoot offsets and is         therefore less dense, when compared to ‘Farah’.
